Method Details
- polar
  
  public static LinePolar2D_F64 polar(List<Point2D_F64> points, @Nullable @Nullable LinePolar2D_F64 ret)
  
  Computes the unweighted best fit line to the set of points using the polar line equation. The solution is optimal in the Euclidean sense, see [1] for more details.

  Parameters:
  
  points - Set of points on the line.
  
  ret - Storage for the line. If null a new line will be declared.
  
  Returns:
  
  Best fit line

  Parameters:
  
  points - Set of points on the line.
  
  weights - Weight for each point. weights[i] ≥ 0
  
  ret - Storage for the line. If null a new line will be declared.
  
  Returns:
  
  Best fit line. or null if sum of weights is zero
